I'm running 8.1, so that could well be the difference there.

I certainly won't say that it's impossible, but I think it's unlikely.
The symptoms mentioned there don't seem related.  Also, the only one
of those programs I'm using is Windows Defender, and I've been using
it for over two years, but this problem only started within the last
few months.  (Of course, I suppose it's possible that something in
Cygwin/gdb/gcc changed to make it more sensitive, or an update to
Windows Defender made it more intrusive...)

Failing a way to keep gdb from doing this, is there a way in gdb to
stop a thread that's in "(running)" state?  (Even though it's sitting
at a breakpoint.)
